+ 3. File save operations have been shown to be slower by as much as 10 times compared to the same project on Kubuntu 20.04 and same version of Gimp.
  A sample project has been created with 200 layers each 4800x7200. When saved with better-but-slower XCF compression the disk file size is around 13 GiB. On the 20.04 system the save time is around 8-15 minutes. On the 22.04 system the save time can be stretched out to several hours.
  A second project tested with 250 larger layers has a save time on 20.04 of just over an hour, on 22.04 it takes more than 12 hours to save.
